I'm envisioning this as a mediawiki, where a given person will have a page, and that page lists claims about things they have said. Edit wars can hopefully be fixed by having a number of editors who know how to be impartial, and being trigger-happy on locking pages so that only they can edit. The talk page can be used for discussion, and for the person themselves to weigh in.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
